Quick Selection Guide - Choose your right pick as per your application

The Challenge

In liquid chromatography, ghost peaks are often unavoidable—especially during gradient elution with buffer salts or acidic additives. These unwanted signals can:

• Interfere with trace and ultra-trace analysis

• Complicate method development

• Delay validation timelines

• Reduce analytical confidence

Identifying and eliminating ghost peaks manually consumes valuable time and resources.

GhostTrap™ is a precision-engineered mobile phase purification column designed to remove trace-level impurities before they reach your analytical column. Built for demanding HPLC and UHPLC workflows, it ensures cleaner baselines, improved reproducibility, and greater confidence in critical data.

The PurePhase Solution

GhostTrap™ Column captures contaminants at the source by purifying the mobile phase inline before it enters the injector and analytical column.

It effectively removes impurities originating from:

• Solvents and buffer systems

• Mobile phase additives and modifiers

• System tubing, mixers, and fluidic components

The result: A cleaner, more stable chromatographic baseline and highly reliable analytical performance.

Key Benefits

✔ Eliminates ghost peaks at the source

✔ Extends analytical column lifetime
✔ Simple inline installation — no system modification required

Proven Performance

Comparative analysis shows that systems equipped with GhostTrap™ demonstrate complete elimination of ghost peaks compared to systems without a trap column.

Even after 600+ consecutive injections, no recurrence of ghost peaks was observed—validating:

• High adsorption efficiency

• Robust loading capacity

• Sustained long-term performance
